Britney Spears' little sister Jamie Lynn tied the knot with fiance James Watson last Friday. After posing for her official wedding pictures, the 22-year-old was quick to change into a pair of comfy Ugg boots.

Jamie Lynn's wedding dress designer Carlos Ramirez shared snaps of his lacy fishtail creation and the beautiful ceremony on his official Instagram account, including shots of the couple's first kiss as husband and wife...

... and a snap of Jamie and her five-year-old daughter Maddie.

But not long after she said "I do" the newlywed had taken down her hair and was back in her Uggs.

Britney, who acted as her younger sister's bridesmaid was also papped in a figure-hugging silver gown.

Well, one thing's for sure, they were certainly showing signs of having a good night.
